Specification of Letters Patent.

Application filed April 24, 191.3.

Patented Nov. 18, 1913.

Serial No. 763,251.

To all whom it may concern Be it known that we, Moses MosLnn, a citizen of the United States, residing at Cincinnati, Hamilton county, Ohio, and CARL BARTELS, a citizen of the United States, residing at Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Safe Construction, of which the following is a specification.

This invention, pertaining to the construction of walls of burglar proof safes, and relating particularly to the construction of non-circular doors of safes constructed mainly of non-cuttable metal such as manganese steel will be readily understood from the following description taken in connection with the accompanying drawings in Which:-

Figure 1 is a rear elevation of a safe door embodying the present invention, a portion of the rear wall-member being broken away to exhibit constructive details in front of it: Fig. 2, a vertical section of the rear doormember in the plane of line a of Figs. 1 and 4: Fig. 8, a vertical longitudinal section of the door in the plane of line a of Figs. 1 and 4; and Fig. 4, a horizontal section of the door in the plane of line Z) of Figs. 1, 2 and 3.

In the drawings :1, indicates the front door-member of the safe, which may be assumed as being formed of such non-outtable metal as manganese steel, the door being rectangular in form: 2, the stepped exterior margins of the door: 3, a recess formed in the rear of the front member of the door by providing the latter with marginal flanges on which the steps are formed, the rear inner surface of this flange being rabbeted on three of its sides and the flange being omitted on the remaining side to the depth of the rabbet: 4, a back-plate forming a rear doormember, the margins of this back-plate fitting within the rabbet of the flange: 5, rearward projections from the main door-member, these projections being positioned well within the margins of the main door member: 6, hooking members projecting from the projections 5 toward that portion of the flange which is cut away to the depth of the rabbet, as before explained, the forwardly presenting faces of these hooks being beveled: 7 hooks projecting from the front face of the rear door-member 4 and having their rear faces beveled to correspond with the beveled faces of hooks 6: 8, lugs projecting inwardly from the flange of the front door-member and having their forwardly presenting faces beveled in correspondence with the bevels of hooks 9: 9, hooks projecting from the front face of rear door-member 4 and engaging in front of lugs 8: 10, a locking-pin passing through the rear door member and engaging over one of the hooking members of the front door-member and serving to maintain all of the hooking devices in proper engagement: 11, a bolt-frame projecting rearwardly from the rear doormember 4; and 12, bolt receiving apertures inthe bolt-frame, after the manner usual in the bolt-frames of square door safes.

The rear door-member 4, practically always of machinable metal, may be properly fitted to the front door-member and then, while separate from the front doormember may be provided with the bolt work and lock work or any of the accessories usual in connection with the rear member of a safe door. When this has been done then the rear door-member 4, together with an accessory carried by it, may be placed within the rabbet of the flange of the front door-member and forced endwise therein, the bevels of the intermembering hooks drawing the rear door-member tightly into place in the rabbet, after which pin 10, which is to be considered only as a typical locking device may be inserted in proper position, thus maintaining the front and rear door-members firmly in proper relative position.

The improved construction has been referred to as safe-construction but it is to be distinctly understood that such construction is applicable to safes of such small size and portable character as are generally referred to as safes, and also to larger fixed safe constructions usually referred to as vaults. In other words, by the expression safe-construction, as used in the present specification and claims, we mean safe and vault construction.

We claim 1. Safe-construction comprising, a main member flanged at its rear to form a rear recess, projections from the rear face thereof provided with hooking members having forwardly presenting faces, lugs projecting inwardly from said flanges and having forwardly presenting faces, a secondary member to be secured to and parallel with the main member and form a rear wall for said recess, projections from the front face of the secondary member provided with projections having hooking members to engage the hooking members of the main member, projections from the front face of the secondary member to engage the lugs on the flanges of the main member, means for limiting the movement of the secondary member toward the main member, and a locking device to maintain the engagement between the hooks'of the secondary member and the hooks and lugs of the main member, combined substantially as set forth.v

'2. Safe-construction comprising, a main member of rectangular form, a flange projectin "rearwardly'from the four margins of the main member, said flange being rela tively lower at one of said margins, a secondarymember to be secured to the rear of the flanged main member and adapted to be margined by the flange of the main member except at the relatively lower margin, intermembering hooking devices at the rear of the main member and at the front of the secondary member, means for limiting the movement of the secondary member toward the main member, and a locking device to maintain the engagement between the hooks of the main and secondary members, combined substantially as set forth.

3. Safe-construction comprising, a main member of rectangular form, a flange projecting rearwardly from the four margins of the main member, said flange being relatively lower at one of said margins and provided with a rear rabbet, a secondary member fitting said rabbet and forming the rear Wall of the recess formed by the flanged main member, intermembering hooking devices at the rear of the main member and the front of the secondary member, and a locking device to maintain the engagement between the hooking devices, combined substantially as set forth.

a. Safe-construction comprising, .a main door-member of rectangular form, flanges projecting rearwardly from two of the side margins of said main door-member and provided at their rear with internal rabbets, a secondary door-member adapted to fit and slide endwise in said rabbets, intermember MOSES MO SLER.
